[SOLVED] Control Volume Methods
Control Volume Methods Purpose:The purpose of this lab is to gain hands-on experience using control volume methods to analyze systems of general and engineering interest.Introduction:Control volume methods provide powerful tools to gain big-picture information about various engineering systems without knowing much about the actual complicated flow patterns within the system.In this lab, you will do two experiments. In Experiment A, you will explore a fairly complex pump / turbine system and use the mechanical energy balance equation along with various physical measurements to approximate losses in the system. You will also determine the overall system efficiency. In Experiment B, you will consider a simple falling liquid jet and apply the integral form of conservation of mass to explain the observed shape of the jet.Include all of your work as an appendix after the Literature Cited section in your report.Experiment A: Efficiency of a Pump/Turbine SystemMaterials:· Pump and Liquid Turbine Apparatus· Ruler· Tape MeasureGiven measurements:· Inner diameter of steel pipe: 1.375 in· Height for Control Surface 2: 19.75 inProcedure:1. Fill the top and bottom tanks high enough that water is just above the base of the weir triangle that connects the tanks. When doing this, make sure that the plug between the upper and lower reservoirs is not inserted into the drain.2. Make sure the tank has a water level matching zero on the flowrate indicator located on the side of the tank.3. Ensure the valve between the pump and turbine is open. Do this by turning the valve four complete counter-clockwise turns (use the blue tape for reference).4. Insert the plug between the upper and lower reservoirs.5. Carefully have a group member walk behind the apparatus and quickly turn the black power dial from 0 to the 3 setting. This is low speed.6. Turn the valve clockwise until the valve is fully closed. The blue tape should be pointing toward the Bourdon gage.7. Turn the valve two full revolutions counter-clockwise (cc).8. Wait at least 15 seconds for the system to reach a steady-state.9. Record the gage pressure head (ft), the flowrate Q (L/s), and the height (in) from the bottom of the lower chamber of the tank to its free surface.10. Repeat Steps 5-8 three additional times, but now, turn the valve one half revolution for each iteration. At the end of this procedure, the valve should be at three and a half revolutions cc from the closed position.11. Turn the black power dial back to the 0 setting.12. Press the circular, red Stop button to shut off the pump.Report Results:· Assuming a constant rate of pump power input (W?P ? 0.5hp), determine an equation (in terms of known quantities) for the rate of mechanical energy lost (W ,1 ) in the section ofthe system stretching from the surface of the bottom reservoir, through the pump, through the piping, and up to the cross-section at the pressure gage.· In Excel or MATLAB, plot W ,1 vs Q using your recorded data and derived equation. Thisgraph should have labeled axes, a title, and a figure number (placed below the graph).· Assuming that the turbine extracts 60% of the mechanical energy input from the cross- section at the pressure gage (?T ? 0.6 ), determine an equation for the total rate of energyoutput by the turbine (WT ) and the overall efficiency of the system (?sys ? W?T W?P ).· In a second graph, plot ?sysvs Q. Once again, include all required labels.Report Discussion:· Comment on sources of error in this experiment.· List and explain all assumptions made to derive the equations used in your analysis. Were these assumptions valid throughout the experiment or only for certain aspects? Explain why or why not.· Comment on probable sources of head loss in the system. Which do you believe were the most substantial? Why?· Were your values of ?sys as expected? Why or why not?· What effect did opening and closing the valve have on the measured pressure, the flow rate, the rate of mechanical energy loss, and the overall system efficiency? Based on your analysis, why is this the case?

Once you have selected a single problem and can define the problem in relation to lean waste, you need to critically analyse the potential solutions formulated from the module and provide considered solutions to the problem, with clear links between the problem and the potential solutions.
[SOLVED] Sensors Technology
Electronic Packaging Fundamentals Course Project ReportAutomotive MEMS and Sensors TechnologyINTRODUCTIONMicro-electromechanical systems (MEMS) are developed as a result of technological advancement in integrated circuits and micromanufacturing, and its technology has become the backbone of many sensor technologies in automobiles. Although faced with many challenges such as device miniaturization, quality, and reliability testing, and high cost from packaging and testing, emerging solutions such as MEMS packaging standardization and wafer level testing can be adopted to overcome these setbacks.LITERATURE REVIEWDevice Miniaturization Device miniaturization has been the ongoing trend in the electronic industry, and the demand for advancement in MEMS technology reflects the drive as well. The recent development in autonomous vehicles and portable devices are calling for higher integration of MEMS sensors to support its increasing capabilities. As these devices increase in function and complexity, the available footprint within the device is continuously limited by the ever-decreasing device size. The manufacturing technique that enables the production of MEMS technology is bulk surface machining, where layers of mechanical structures and features are created through a combination of etching and layer deposition. As the demand for smaller and more intricate features rises, the industry must provide an answer in terms of improved and more advanced manufacturing techniques to address the miniaturization trend.Component Testing Many MEMS devices serve as accelerometers, gyroscopes, and sensors for critical data acquisition applications; therefore, the reliability and quality of these devices must be ensured. Extensive reliability testing is performed at the device or package level to ensure that the product meets requirements and specifications. When it comes to testing MEMS products, both electrical and mechanical analysis is required for a thorough examination of the product performance. The coupling relationship of the mechanical parts with electrical circuitry results in a complex system that requires unique testing equipment. The cost of testing equipment and setups such as testing stations can easily exceed millions of dollars in capital investment from the device manufacturer. The Challenge of high testing cost poses a roadblock in the MEMS market and innovative solutions are needed for a cost-saving solution.MEMS and CMOS Integration As shown in Fig. 1, MEMS structure is often coupled with integrated circuitry to perform sensing and analysis of the acquired data. The industry’s drive to lower the production cost and device size calls for the tackling of the challenge in MEMS and CMOS process integration. The current method for system integration involves the manufacturing of the MEMS and electrical circuitry on different substrates, and interconnects or direct bonding of the two chips are performed for device integration. This approached is forced by the high cost associated with monolithic integration. Challenges foreseen within the industry would be to lower the cost associated with the integration of MEMS with IC fabrication.

[SOLVED] Customer Interview Reports
Customer Interview Reports Customer Interview 1Project Description For this interview, we discussed the practicality and market need for a tool to aid in the remotediagnosis of strokes via telemedicine. The tool is a wearable device worn on the face that allowsa specialist to remotely assess the visual fields of a patient.Interviewee: Mary Britton | Stroke Coordinator, Promedica Health SystemInterview Summary Mary Britton, the stroke coordinator for the regional NW Ohio area, was chosen for thisinterview due to her extensive knowledge on the topic of strokes and her familiarity with theneed for a swift diagnosis. She also has experience with a wide variety of stroke and post-strokecare techniques. Her experience and perspective will be helpful to us for finding a niche for theproduct within the diagnosis, analysis, and recovery process of stroke patients.After explaining the utility of the device to Mary, she offered her opinions on how thedevice could be implemented within the stroke diagnosis process. She stated that the use oftelemedicine for the diagnosis of strokes is growing tremendously. Currently, EMTs in the fieldare using iPads to connect with specialists from the ambulance. They are able to communicatewith the neurologist and ask questions as well as take instructions to help diagnose the patient onthe way to the hospital. There is even a mobile stroke unit that includes specially-trained EMTsand an ambulance with a working CT scanner inside. These tools have improved the time todiagnosis and time to treatment for severe or acute stroke cases. In general, if the EMS thinkthe patient is experiencing a stroke, preparations are made at the hospital while the patient is intransport to allow them to be diagnosed and treated as quickly as possible. This includesprepping the CT scanner and IV access for the incoming patient. In almost all cases that an EMTsuspects a stroke, the patient undergoes a CT scan. The CT scan is a much more reliable test thathelps doctors determine if the stroke is Ischemic or Hemorrhagic. Ischemic means there is ablockage in the brain, hemorrhagic means there is bleeding in the brain. After the CT Scanconcludes that the stroke is not Hemorrhagic, and the patients last known normal was less than 4hours before diagnosis, the patient is given TPA, a clot-busting injection. This breaks up the clotthat is causing the Ischemic Stroke. This distinction is important as TPA could be life threateningto a hemorrhagic stroke victim.There is a standard field diagnosis technique, called the National Institute of Health(NIH) Stroke Scale, EMTs use this technique to preliminarily diagnose the severity of the strokein the patient. This stroke assessment works well enough for severe strokes and yields a strongconfidence that a stroke is occurring. Mary indicated that since this test reliably indicates a strokeis occurring, the Telestroke Goggles would not improve this process. She did explain to us that amore feasible and useful application for the Telestroke Goggles: the case of the minor stroke.Often times, if a patient is not exhibiting the symptoms of a severe stroke, they are notimmediately transported to Toledo hospital and are monitored for 23 hours in the rural clinic.Since it is not as easy to detect if the patient is having a minor stroke, the tool can be useful toget a more accurate depiction of the visual field loss of the patient. At these clinics there are nospecialists available so the telemedicine aspect of the device will allow nurses to apply thedevice and a specialist can carry out the test remotely. Mary also said the device could be usedpost-treatment to determine if the visual field loss has improved in patients. The minor strokecase can often be confused for post-migraine, post-seizure, or encephalopathic symptoms.Patients can even misleadingly exhibit stroke-like symptoms if they have a psychologicacondition called conversion disorder. Having this device at the fingertips of these clinics willallow the minor stroke cases to be easily sorted out from the false positives.Conclusion Overall, Marys comments helped us realign our market focus towards the minor strokecase. She did not have any improvement comments on the device itself. She believed theprinciple diagnosis method of the device to be correct and that the device would serve a marketneed in a rural clinical setting.
